Jtdx 2.2.160 Jun 2026

JTDX is known for pulling extremely weak signals out of the noise. The 2.2.160 release optimizes this further:

| | RC Version | Change Description | | :--- | :--- | :--- | | FT8 Decoding | RC10, RC3, RC7 | Improved signal decoding, prevented false decodes at edges, and reduced crashes. | | Security | RC10 | Implemented password-protected ZIP archives for Windows builds to prevent unauthorized access. | | Hamlib | RC10 | Upgraded from Hamlib 4 to Hamlib 5 for improved radio control compatibility. | | DXpedition | RC10 | Enhanced special messaging mode and blocked activation if auto-logging is on to prevent conflicts. | | GUI | RC3, RC7 | Optimized main window, similar to wsjt-x_improved AL, and added band/mode selection checkboxes. | | Bug Fixes | RC10, RC3 | Fixed buffer overflows, report message creation, partial message filters, and custom UI issues. | | Platform | RC7 | Made a macOS version for Apple Silicon (arm64) available for the first time. |

We’ve all been there: a weak EU station on 40m, fading in and out like a candle in wind. 2.2.160’s soft-decision FEC and iterative decoding pull messages out of near-noise floors that would make WSJT-X throw a timeout error.

Hi all,

Whether you operate primarily ?

: Upgraded dynamic integration via the Hamlib SDK resolves critical time-out and connection Drops with modern HF transceivers.

4.1. Front-End and Preprocessing

: Includes fixes for exact frequencies in QSO logging and restoration of the ReplyTx state if a QSO is interrupted. UI Enhancements : New tooltips for Enable Tx , Sync , and AGCc buttons. Display of time offset directly on the Sync button.

JTDX is a highly popular, open-source software program used by amateur radio (ham radio) operators for making digital voice and data contacts over HF (High Frequency) and VHF/UHF bands. It is specifically designed for "weak signal" communication, meaning it can decode radio transmissions that are too faint for human ears to understand.

Whether you are working rare grid squares on 6 meters or digging out critical contacts through the noise on 160 meters, understanding this software version is essential for competitive digital operation. The JTDX Advantage vs. WSJT-X
